1 Claim. l

This invention relates to bobby pins, and the main object is theprovision of a double bobby pin substantially in the form of a attenedS, that is, one formed of a unitary length or strip of material havingboth ends thereof from points spaced approximately one-third of thelength of the strip doubled back against opposite sides of the centralportion of the strip, both the said end lengths being provided withwave-like corrugations.

Bobby pins in common use are of the general form of a U and hence areprone to slip out of place endwise, whereas the double bobby pin of thisinvention will not easily slip out of place because it comprises ineiect two opposed U- shaped bobby pins both having one arm of its U incommon and because the hair is engaged in both of the Us thereof.Consequently, this double bobby pin will hold the hair permanently.

The double bobby pin of this invention also serves as a curl (wave)fastener and is therefore especially useful in making artificialpermanent waves.

The above as well as additional objects will be claried in the followingdescription, wherein characters of reference refer to like-numberedparts in the accompanying drawing. It is to be noted that the drowing isintended solely for the purpose of illustration and that it is thereforeneither desired nor intended to limit the invention, as disclosed, toany or all of the exact details of construction shown or describedexcept insofar as they may be deemed essential to the invention.

Referring brieily to the drawing, Fig. 1 is a perspective View of thedouble bobby pin of this invention.

Fig. 2 is a top View of the pin of Fig. l.

Fig. 3 is a side elevational view of the same.

Fig. 4 is a perspective view of a modified form of the double bobby pin.

Referring in detail to the drawing, the numeral IU indicates a completedouble bobby pin constructed in accordance with the teaching of thisinvention, in any desired manner, out of a single strip of resilientmaterial of any suitable kind or type.

The completed pin comprises a mid-portion i I which is positionedbetween the two end portions I2 and I 3 which are normally urged by theresiliency of the material against and substantially into contact withthe mid-portion. The end portions I2 and I3 of the pin are identicalexcept that they extend in opposite directions from the extremities ofthe mid-portion II.

The bights I4 are formed between the end portions and the mid-portionand are rounded and elongated, substantially as shown, the end portionsI2 and I3 being each provided with a series of substantially identicalwaves or corrugations I5. In the normal position of the several portionsof the pin, when not in use, the end portions I2 and I3 are spacedequidistant from each other throughout their length, or, in other words,the crests of the corrugations I5 of one end member are positioneddirectly under the troughs of the corrugations of the other end member,as is apparent in Figs. 1 and 3.

Fig. 4 shows a modified form of the double bobby pin Illa, wherein theonly diierence is that the pin is constructed of a single length of wireinstead of a strip as in the form previously described.

It is apparent that when a lock or strand of hair is clamped between theend member I2 and the mid-portion II and another strand of hair isclamped between the other end member I2 and the mid-portion II, the pinwill be restrained from slipping longitudinally, which condition doesnot exist in the case of the cornmon U-shaped bobby pin having one endthereof open so that the pin may slip completely away from the strand ofhair.

Obviously, modifications in form or structure may be made withoutdeparting from the spirit or scope of the invention.

I claim:

A double bobby pin comprising a unitary length of material ofsubstantially constant cross-sectional dimensions comprising amid-portion of approximately one-third the length of said unitary lengthand having the ends each approximately equalling the length of saidmid-portion and doubled back against the opposite sides of saidmid-portion, said ends having wave-like corrugations formed thereonthroughout their length, bights formed at the extremities of saidmid-portion by the doubling back of said ends as aforesaid, said bightsbeing rounded, that portion of each of said end portions adjacent one ofsaid bights being straight and extending at an acute angle with respectto said midportion and further having a length'equal at least to thelength of two of said corrugations.

ISIDOR ATTIAS.
